HEEL-TmMMINe MACHINE.

SPECILFICATION :forming part o1' Letters Patent No, 315,203, dated April 7, 1885.

Y Application filed February 13, 1885. (No model.)

To @ZZ whom, it may concern: Y

Be it known that I, DANIEL A. WILLIAM- soN, a citizen of the United States, residing at Watsontown, in the county of Northumberland and State of Pennsylvania,have invented a new and useful Improvement in Heel-Trinimers, of which the followingis aspecication, reference being had to the accompanying draw ings.

My invention relates to an improvement in heel-trimmers for boots and shoes; and it consists in the peculiar construction and combination of devices that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a perspective view of a machine embodying my invention. Fig. 2 is a vertical transverse sectional View of the same, taken on the line x x of Fig. 1. Fig. 3is a detailed perspective of the pivoted arm and its swiveled extension.

A represents a stand, to which is journaled ashaft,B,which is provided with a large driving-pulley, C, and a fast pulley, D, and loose pulley E. On the upper side of the stand near one end is bolted a cast bracket or standard, F, which is provided with a horizontal rearward extension, to which is secured a bearingblock, f. At t-he opposite end of the stand, on its upper side, is bolted a cast bracket or standard, G, which is provided with a horizontal rearward extensiomto which is secured a bearing-block, g.

In the blocks fand g is journaled a shaft, H, to which is made fast the pulleys I and K. The pulley I is connected with the pulley Gby a belt, Z.

Pivoted on the shaft H is an arm, L, to which is swiveled an extension, L', as at Z. A shaft, M, is journaled in the outer end of the eXtension L at right angles thereto. A fast pulley, m, is secured to one end of the shaft M, and to its opposite end is secured a cutter-head, m', and a welt-burnisher, m2. The extension L is provided with a T-shaped head, in which the shaft M is journaled, and over this head, adjacent to the cutter-head, is placed a yoke, N, which is adapted to slide vertically on the head of the-extension, and is controlled by a screw, u, which extends down through the upper side of the yoke, and has its lower end bearing on the upper side of the head of the extension L. A bent handle-rod, Z, projects upwardly from the extension L', and by means of this bent rod,'which is adapted to be grasped by the left hand of the operator, the arm may be raised or lowered, and its swiveled outer extension inclined in either direction,as will be very easily understood.

O represents a frame which is hinged to the stand A at one end adjacent to the standard G, and in the free upper end of this hinged frame is journaled a rock-shaft, P, which has a crank, p, at its outer end. A curved abutment, g', is secured to the outer side of the standard G, and to the shaft Pis fixed a curved camlarm, R, which bears against the abutment g. A die, S, which corresponds in shape to the heel that the machineis designed to trim, is secured to the inner end of the rock-shaft, and turns with the rockshaft. The yoke N bears against the die when the machine is in operation. vided with a fla-nge, s, and the outer face of the die has a stop, s', against which is placed the square front portion of the heel to be trimmed. An arm, T, extends from the rockshaft, and is keyed thereto, and this arm is curved, as shown, and toits outer end is pivoted a sleeve, t, the center of which is on a line with the center of the rock-shaft. A screw, V, passes through the pivoted sleeve, has a bearing-head, v, at its inner end, and a handwheel, e', at its outer end, as shown.

The operation of my invention is as follows: The boot or shoe of which the heel is to be shaped and finished is placed with bottom of its heel bearing against the outer side of the die, and is clamped in place against the die by the screw V, one side of the sole of the shoe bearing against the arm T, as at y. Motion is imparted to the machine, and the operator grasps the crank p with his right hand and slowly rotates the rock-shaft, while with his left hand he grasps the handle-rod Z, and causes the cutter-head to bear against the edge of the heel t'o be trimmed. Motion is imparted to this cutter-head by means of a belt, h,which connects the pulleys K and m. The knives of the cutter-head shape the heel as the crank- The outer side of the die is pro- ICO shaft is being turned, and when the bearingyoke reaches'the point fw of the die the heel is finished and the shoe is removed. The adjustable yoke which bears against the side of the die regulates the depth ofthe out of the cutterhead, and thus adapts the machine for use in trimming heels of any desired size. Dies of different sizes will, of course, be required in order to make different sizes of heels.- The burnisher m2 enters the seam betweerf the heel and the upper and shapes and burnishes said seam. The arm R limits the movement of the rock-shaft. Vhen the cutter-head is in motion, and it is not desired that it should bear against the heel, as when the shoe is being placed upon the' machine or removed therefrom, the' arm L L is raised and supported upon the upper bent end of a supporting-rod, W, that'is pivoted to the stand7 as at z.

Having thus described my invention, I claim'- 1. The combination of the rock-shaft having the die, the pivoted arm having the swiveled extension, and the cutter-head journaled to said extension, substantially as described.

2. The combination of the rock-shaft having the die, the pivoted arm having the swiveled extension, the cutter-head journalcd to said extension, and the sliding yoke, and the screw for controlling the yoke, substantially as described.

3. The combination of the hinged frame, the rock-shaft journaled in saidframe, and having the die, and a clamp for securing the heel of the shoe against the die, with the pivoted arm having the cutter-head and the yoke for bearing against the die to guide the cutterhead, substantially as described.V

4L. The combination. of the hinged frame,the rock-shaft journaled in said framefand having the die, and a clamp for securing the heel of the shoe against the die, with the pivoted arm having the swiveled extension, the cutterhead journaled in said extension, andthe sliding yoke for bearing against the die, for the purpose set forth, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
